Here is two of my rarest Nike boots! First is the very sought after Nike Mercurial Superfly I “Wear It Proud” made only 70 pairs worldwide, I got the 05/70 Tom Varndell’s boots!
Second boot is Nike Mercurial Vapor IX CR7 SE100, only 100 pairs were made to celebrate Cristiano Ronaldo and his accomplishments during 2012! This is why the boot got a row of different numbers on the heel:

1 first Spanish championship
9 goals for Portugal
14 games played for the national team
19 the first player to score against all 19 La-Liga teams
27 years old in 2012
55 games played in all tournaments for his club
60 goals scored in all tournaments for his club
